一种新型五路功率分配/合成网络设计
Design of a novel five-way power dividing/combining network
摘要
Abstract
In order to overcome the deficiencies of existing five-way power dividers/combiners,a novel Ku-band five-way power divider/combiner with high isolation was proposed.The structure is composed of a branch-line waveguide three-way power divider,an Ω-shaped waveguide phase shifter,a coplanar magic-T,a compact corner waveguide,and a waveguide matched load.An Ω-shaped stepped waveguide phase shifter was proposed to precisely adjust the phase response over a wide frequency range.The structure was modeled and optimized using the three-dimensional electromagnetic simulation software HFSS.Two samples of the five-way power divider/combiner were fabricated and measured,and the measured results were in good agreement with the simulation results.Furthermore,a novel Ku-band five-way power dividing/combining network was constructed by connecting two five-way power dividers/combiners back-to-back.The measured results show that the transmission loss of the network is less than 0.2 dB,the return loss is better than 16 dB across the frequency range of 13.75-14.5 GHz,and the power combining efficiency is greater than 97.7%.This network demonstrates high performance and provides a promising solution for Ku-band power combining applications.关键词
